Prince Arin is the son of King Nogburt.
He met Teddy and Gimmick
in the Mudblup dungeon. He met Grubby when the three of them rescued
him from the Mudblups. He told them of his lost sister, Princess
Aruzia who had been kidnapped. They helped him get her back
and they've been welcome at the castle ever since. The castle
later became of greater importance when Arin finds the Crystal
Book in a small opening under the castle. It's also where the
life of the King is saved. Arin also helps get Grubby and Gimmick
out of M.A.V.O. (The Monsters and Villans Organization).
